Calculation method and calculation apparatus for general-drawing earthwork volume of oil and gas storage and transportation station

Abstract

The invention discloses a calculation method for a general-drawing earthwork volume of an oil and gas storage and transportation station. The method comprises the following steps: calculating a field earthwork volume and calculating a structure earthwork volume, wherein a calculation method of the field earthwork volume comprises the following steps: forming an original topographic map; converting and generating a terrain surface; drawing a field boundary line; connecting the field boundary line with the terrain surface; generating a design surface; calculating a difference value between the design surface and the terrain surface to generate the field earthwork volume; and a calculation method of the structure earthwork volume comprises the following steps: generating a structure cross-section model; generating an assembly; forming a structure route and a longitudinal section; generating a structure three-dimensional model; determining a structure earthwork calculation formula based on a sampling line; and generating the structure earthwork volume. The invention also provides a calculation apparatus for the general-drawing earthwork volume of the oil and gas storage and transportation station. The alculation method and the calculation apparatus have the beneficial effects that the calculation precision is improved, and calculation error caused by the shortage of standard height acquisition information and manual estimation can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a calculation method and a calculation device for the earthwork quantity of an oil and gas storage and transportation station general plan. Background technique [0002] At present, the earthwork volume of the general plan of oil and gas storage and transportation stations mainly consists of two parts. The design contour is drawn on the basis of the points, and the design contour is discretely generated into several design elevation points, and then the earthwork quantity of the site is generated by calculating the difference between the design elevation point and the elevation point of the original topographic map; the other part is the general map The earthwork quantity of structures such as roads, fences, and retaining walls is mainly estimated, and the earthwork quantity of earthwork filling and excavation of the structure is obtained by multiplying the route length...

AI Technical Summary

Problems solved by technology

[0003] The earthwork quantity of the general plan professional site design is mainly calculated by the two-dimensional earthwork grid method, which has two main defects: first, the two-dimensional earthwork grid method can only be calculated from the simple From the perspective of the plan view, the three values ​​of the original elevation, the design elevation, and the filling and excavation height of the four corner points of the grid reflect the situation of the site design filling and excavation, and there is no way to reflect the actual situation of the general earthwork calculation in a more intuitive way; , the corner points on the grid cannot cover the elevation information of each point in the design site, and the results are prone to errors when generating the grid for earthwork calculation

There are also two defects in the calculation of earthwork filling and excavation for the design of roads, fences, retaining walls and other structures in the general plan through the estimation method: one is that the estimation process cannot be reflected in a more intuitive way; The design elevation changes dynamically with the design elevation of the site, and there will be errors between the result obtained by simply multiplying a fixed cross-sectional area by the route length and the actual situation
